WHY A MARTINGALE?
Secure when needed. Relaxed when it isn’t.
A martingale is a limited-slip collar. It sits relaxed during normal wear and reduces its opening when leash tension is applied, helping prevent a dog from backing out of the collar.
The standard EDG martingale is built without a buckle, so it must pass over the widest part of the head and then adjust at the neck. If you add the Tactical Buckle, the collar opens instead and neck measurement drives the size.
The goal is secure, properly fitted movement—not continuous pressure.
